Removing Singularities
Shmuel Elitzur, Amit Giveon, Eliezer Rabinovici
Big bang/crunch curvature singularities in exact CFT string backgrounds can be removed by turning on gauge fields. This is described within a family of {SL(2)xSU(2)xU(1)_x}/{U(1)xU…
Remarks on Black Hole Instabilities and Closed String Tachyons
J. L. F. Barbon, E. Rabinovici
Physical arguments stemming from the theory of black-hole thermodynamics are used to put constraints on the dynamics of closed-string tachyon condensation in Scherk--Schwarz compac…
Les Houches lectures on supersymmetric Gauge Theories
D. S. Berman, E. Rabinovici
We introduce simple and more advanced concepts that have played a key role in the development of supersymmetric systems. This is done by first describing various supersymmetric qua…
From Big Bang to Big Crunch and Beyond
S. Elitzur, A. Giveon, D. Kutasov +1
We study a quotient Conformal Field Theory, which describes a 3+1 dimensional cosmological spacetime. Part of this spacetime is the Nappi-Witten (NW) universe, which starts at a ``…
Closed-String Tachyons and the Hagedorn Transition in AdS Space
J. L. F. Barbon, E. Rabinovici
We discuss some aspects of the behaviour of a string gas at the Hagedorn temperature from a Euclidean point of view. Using AdS space as an infrared regulator, the Hagedorn tachyon…
